Bug Description

The installer (in 16.04 and 17.10) creates a separate /boot partition, when required, of only 487M. This ends up being rather small when you using the following equation to estimate a minimal size allowing for reasonable room for further growth.

(2*(3*kernel + 4*plymouth-carrying initrd + bootloader))

for Kernels of 8Mb, initrd of 55Mb and bootloader of ~10Mb:

2* ( 3*8 + 4*55 + 10 )
2* ( 24 + 220 + 10 )
2* ( 254 )

We're slightly off with the math right now, so I'll make the absolute minimum size for /boot to be 512Mb; and bump the maximum from 512 to 768. This should give us partition sizes of a little over 512, probably around 650Mb (so some room for future kernel/initrd growth).
